Patent number: 4963158Abstract: Soiled textile articles are washed by the addition of a determined amount of a detergent concentrate containing surfactants to the textile articles to be cleaned while the textiles are dry or only damp. The aqueous washing liquor is formed by the gradual addition of water to the textile articles while they are rotated. At room temperature, the detergent concentrate is to a substantial extent a paste-to dough-like substance, stable in form, and is applied to the textile articles in such an amount that the major portion of the surfactants together with further detergent constituents, if desired, are applied to the textiles or on an article of textile provided with markings for the correct detergent dose, as a dosing aid.Type: GrantFiled: February 8, 1989Date of Patent: October 16, 1990Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Hans-Josef Beaujean, Horst Eisenblaetter, Johann F.
